SPECIFICATION forming part of Letters Patent No. 700,896, dated May 2'7, 1902.

Application filed March 14, 1898. Serial No. 673,786. (No model.)

To aZZ whom it may concern: sets of cash-keys there are shown in the pres- Be it known that I, THOMAS OARNEY, a citient instance four special keys, one of which, zen of the United States, residing at Dayton, marked Paid out,is located at the extreme in the county of Montgomery, in the State of right of the cash keys, another of which,

Projecting from the side of each of such extensions or fingers G is a stud or pin J. These studs or pins upon the fingers G of the keylevers in each series or group are arranged in graduated order or at graduated distances from the upper ends of the fingers of the re spec'tive levers, the pin upon the right-hand lever in each series (which is the key-lever of lowest value in each series) being located at the greatest distance from the upper end of the finger of such lever, while the pin upon the left-hand lever (being the lever of highest value) is located nearest the upper end of the finger G of the lever, and the pins upon the intermediate levers are locatedin regular order between these lowest and highest points. In Fig. 6 the pin J shown in full. lines is the pin upon the right-hand key-lever in the lefthand or dollar series, as will be apparent from the dotted line 6 6 in Fig. 1, and the locations of the pins J upon the remaining eight levers in the series are indicated by dotted lines. In Fig. 5 the viewis taken immediately at the left of the sixth or sixty-cent key in the middle group, (see dotted line 5 5 of Fig. 1,) so that the locations of the pins J upon the six keys to the right are shown in dotted lines. In Fig. at the view is taken immediately at the left of the second key in the right-hand group, so that the location of the pins J on the two keys at the right are shown in dotted lines on Fig. 4t. The arrangement of the pins upon the levers of the several groups is also clearly shown in Fig. 3.

It results from the foregoing construction and arrangement of the parts that when the front end of any key-lever is depressed and its rear end lifted the upper end of its extension or finger G will enter one of the vertical slots 0 in the bar or frame Icorresponding to the group of keys to which the operated key belongs, and the laterally-projecting pin .I upon the finger Gof such lever will enter the horizontal slot b in the bar I, and thereby couple the key-lever to said bar and cause the rear end of the latter to be swung upward and for 'ard by the further upward and forward movement of the finger G of the key-lever. Inasmuch as the key-lever becomes securely coupled to the bar I as soon as the pin J of such lever enters the horizontal slot 1) in the bar, it follows that during the further movement of the parts the keylever and bar are locked together and compelled to move in perfect unison. Owing to the grad uated arrangement of the pins J upon the keylevers, it follows that the lever of highest value in each series will give the bar or frame I its maximum movement and each of the other levers a less movement proportionate to its assigned value. The full depression of the front end. of any one of the cash-key levers will therefore move the corresponding bar or frame I a distance corresponding to the exact value of such lever. As hereinafter described, a complete stroke mechanism is provided for compelling the full downward movement of the front end of any keylever which is started to thereby insure the full proper movement of the corresponding bar or frame I whenever any key-lever is operated. v

The left-hand one of the three frames I (the right-hand one in Fig. 3) is fast upon the rock-shaft .lI, while the other two are loosely hung upon said shaft and free to be swung upward and downward under the action of their cooperating key-levers without movement of the shaft. llfoving with each of the rocking frames I is a sector-rack K. As shown in Figs. 1, 2, and 3, the racks K of the three rocking frames are grouped closely together, to which end the right-hand one of the three racks is fixed to the left-hand end. of the first or right-hand frame I, while the next or middle one of the three racks is fixed to the right-hand end of the middle frame I. The left-hand one of the three racks is fast upon the shaft H at a considerable distance to the right of the left-hand .frame I. In normal position the upper rear ends of the racks rest against abutments upon a bracket-frame L, Figs. 2 and 5, secured to and dependent from the cross-plate M of the framework.

Mounted upon a rod N, fixed at its opposite ends in the frame-plates O 0, Figs. 2 and 5, is the usual rocking registering-frame P, in the upper part of which is mounted the shaft upon which are supported the registering-wheels Q, Fig. l. The three racks K are adapted to cooperate with the pinions of the three righthand registeringwheels Q, to which end the frame I, carrying the registering-wheels,is rocked backward and forward at each operation of the machine to engage the pinions with and disengage them from the racks. For this purpose the rocking registering-frame P has secured to its right-hand side a forwardly-projecting arm B, Fig. 1, which is provided with a laterally-projecting stud which fits in a cam-groove in a disk S, Figs. 1. and 5, fast upon a rotary shaft T, extending transversely across the machine and journalcd at its op osite ends in the side frames thereof. This shaft is given a complete turn at each operation of the machine in the manner and by the means hereinafter described,with the result that at the beginning of the downward movement of any key-lever the registering-frame I will be thrown rearward to bring the pinions of the registeringwheels into position to be engaged by the racks K and at the beginning of the return upward movement of the lever the frame I will be rocked forward to normal position again, thisgeneral. mode of cooperation between the racks and the rocking registeringframe and registering-wheels being substantially the same as that in machines heretofore patented to me and now in extensive use.

The means for rotating the shaft T is shown in Fig. 4, where it will be seen that a lever U, fulcruined to the framework at its rear end at V, has a slot-and-pin connection with the universal bar F at W and a similar connection at its forward end with avertically-reeiprocating rack-plate X, mounted in guides Y upon the side plate of the framework. The shaft T has fast upon it a seetor-pinion Z, provided with a spring-tooth Z and cooperating with the opposite racks of the vertically-reciprocating plate X in the well-known manner to cause the reciprocations of said plate to revolve the shaft T. Theconnection of the plate X with the universal bar F causes the plate to be reciprocated by the operations of the key-levers and the shaft T to be thereby given a complete revolution at each operation of any one of said levers.

The rotary shaft T has fast upon it a ratchet A, Fig. l, with which cooperates a pawl 13 to prevent backward movement of the shaft. Inasmuch as the bar F is connected through the medium of the lever U, the plate X, and pinion Z with the shaft T, it follows that the ratchet and pawl above referred to serve as a complete-stroke mechanism for the operated key-levers, requiring afull downward movement of each of the operated levers before it can return to normal position, this general form of complete-stroke device for the keylevers of cash-registers being, however, old and well known.

Locatedat the left of the main register of the machine are four special registers 0, Figs. 1 and 2, with which cooperate, respectively, the four special keys shown in Fig. 1 and hereto fore referred to. Journaled in the frameplates 0, Fig. l, and extending therefrom to the left-hand side of the machine is a rockshaft D, upon which are mounted two sleeves E F. Fast upon the right-hand end of the sleeve E is a depending arm G, Figs. 2 and 5, which fits between two pins H, projecting from the side of the special key marked It. on acct. in Fig. 1, so that whenever said key is depressed the lower end of the arm G will be swung rearwardly and the sleeve E turned accordingly. The rock-shaft D has a similar arm G secured upon its extreme right-hand end and adapted to cooperate in the same manner with pins upon the special key marked Paid out, while the sleeve F is provided with a similar arm cooperating with pins upon the key marked Charge, allas shown in Fig. 2. 0n each of the sleeves E and F is arearwardly-projecting arm I, Fig. 1, while fast upon the shaft D at the left of the sleeve F is a third similar arm 1. Loose upon the shaft D at the left of the last-mentioned arm I is a fourth similar arm 1, to which is rigidly secured a depending arm G, corresponding to the arms G heretofore described, Fig. 2, these two last-mentioned arms G and I together constituting a bell-crank loose upon the shaft D and cooperating with the lefthand special key marked No sale. The

actuating-pawls J for the respective sets of registering-wheels O are carried by the vertical arms K of bell-crank levers fulcrumed on the horizontal shaft L, Fig. 2, and the forwardly-proj ectin g horizontal arms 1" Fig. 7, of which bell-cranks are provided with laterally-projecting pins or studs N, fitting in slots in the rear ends of the arm I heretofore described, Fig. 1. Vhenever any one of the special keys is depressed, the rear -end of the connected arm I will be thrown upward,thereby rocking the bell-crank K M, carrying the pawl cooperating with the corresponding register C, and throwing said pawl rearward and causing it to register a unit upon such register. In this manner the four registers for the four special keys are compactly arranged at one side of the machine and each is actuated by the operation of its corresponding key to preserve a record of the number of operations of the respective special keys, as usual.

The foregoing completes the description of the registering devices of the machine, leaving the indicating devices to be described as follows:

The machine is shown provided with two sets of indicator-wheels O P, Fig. 2. Each set contains three indicator-wheels, one wheel for each group or set of key-levers. The wheels in the lower set are adapted to expose their numbers at sight-openings in the forward side of the casing, while the wheels in the upper set expose their numbers at sightopenings in the rear side of the casing. To this end the numbers upon the wheels in the two sets are arranged in reverse order, and the wheels are so connected with each other, as hereinafter described, that the two wheels representing each denomination of value move in unison with each other, so that when one of them is turned to display a given number at the forward side of the casing the other will display a corresponding number at the rear side of the casing.

Secured to and depending from the under side of the horizontal frame-plate M, Figs. 2, 5, and 6, are three bracket-bearings Q, in each of which is journaled a vertical spindle R. (Shown by dotted lines within the bearing Q in Figs. 5 and 6.) Fast upon each spindle R immediately beneath its bearing Q is a pinion S, while fast upon it immediately above its bearing Q is a collar T. Each collar T is provided with a horizontally-projecting arm U, which is provided with a vertical projection or stud V, Figs. 5 and 6, adapted to cooperate with a horizontal arm WV, project ing from the lower end of a sleeve X, fast upon a vertical spindle Y. (Shown by dotted lines in Figs. 5 and 6.) The extreme upper end of the Vertical spindle Y is journaled in the top plate Z as shown in Fig. 1, while the reduced lower end of the spindle projects below the sleeve X and is seated in a bore in the upper end of the spindle R, as clearly shown in dotted lines in Figs. 5 and 6. The

wheel returns toward normal position.

indicator-wheels P in the lower set are fast upon the upper end of the sleeves X, secured to the spindles Y.

The pinions S, fast upon the lower ends of the spindles R, mesh with sector-racks A carried by the rocking frames I, heretofore described, there being three of the sectorraeks A one carried by each of the frames 1, as shown in Figs. 2 and 2-3. The pinion S upon the lower end of the middle spindle B does not mesh directly with the middle rack A Fig. 2, but through the medium of an in termediate pinion S, fast upon a stub-spindle journaled in the bracket-bearing Q, this intermediate pinion being provided merely to permit the middle rack A to be located farther to the left than would otherwise be necessary, such location of the rack A in the present instance being a convenient one in the particular machine shown.

It results from the foregoing; that when a key-lever in any given group is depressed the corresponding rack A will be thrown forward and will turn the spindle R. WVhen the spindle R is so turned, the pin V, carried by its arm U, will contact with the arm \V of the sleeve X, which carries the corresponding lower indicator wheel P, and will consequently cause said indicatorwheel to be turned forward with the spindle R. It will be understood, however, that the spindle R can return to normal position independently of the indicator-wheel, so that during the return movement of the parts the indicatorwheel may be arrested at any desired point by suitable means and the operated key-lever and spindle It and intermediate connections permitted to move on to normal position alone. In the manner and by the means to be now described the indicator is arrested during its return movement at the proper point to expose to View its number corresponding to the value of the operated key-lever and is held in such position until the key-lever and connected parts return to normal position and until some key -lever is again operated at the succeeding operation of the machine. Each of the sleeves X has fast upon it a pinion 13 which meshes with a rack-leverC resting upon and pivoted to the upper side of the frame-plate M and provided with a rearwardly-projecting arm D Fig. 1. At the downward movement of the front end of any key-lever and the forward movement of the corresponding indicator P the arm D of the rack-lever C will be swung to the left and will return toward the right as the indicator- I10- cated across the rear side of the machine is a row of vertical indieatonrods E one for and vertically above the rear end of each keylever A. At their upper ends these indieatorrods E are supported and guided in holes in the horizontal frame-plate H, while the reduced lower ends of the rods are guided in and project downwardly through holes in a cross-bar F of the framework, Figs. 5 and (3,

the shoulders formed upon the rods at the junction of their red need lower ends with the bodies of the rods normally resting upon the upper side of the bar F and serving to support the rods vertically upon said bar. Each rod has fixed to it near its upper end a collar G which is provided with a forwardly-projecting horizontal arm 11 which carries a vertical pin 1 extending upwardly through a hole in the plate M, Fig. (3. A spring J,

surrounding the rod E between its collar G and the under side of the plate M, presses the rod downward and aids gravity in holding it in and returning it to normal position. Each of the collars G is provided upon its rear side with a notch in which normally rests the upper forward edge of the pivoted supporting bar or wing K hen the front end of any keylever A is depressed, its rear end as it approaches its limit of upward movement will contact with the lower end of the correspondin rod E below the cross-bar F and lift said rod, which will project its pin 1 above the plate M, and will also carry its collar G above the supporting-wing K whereupon the latter will catch under the collar and support the rod E in elevated position until the upper. edge of the wing is thrown rearward and disengaged from the collar. Depending from the wing K at one end is an arm L which has a slot-and-pin connection with the upper rear end of a lever M, Fig. (3, whose forward end cooperates with a cam N fast upon the rotaryshaft T, heretofore described. At each operation of the machine and complete revolution of the shaft '1 the cam N will depress the front end of the lever M and thereby rock the wing K and throw its upper edge rearward to release the elevated rod or rods E after which the wing will be pulled forward to normal position again by the coiled spring 0 Fig. (3.

The pins 1 carried by the indicator-rods E constitute stops for arresting the indicator-wheels at different points in their return movements toward normal position, to which end the pins 1 cooperate in the following manner with the arms D of the levers C, which are geared to the indicator-wheels, as before described. Referring to Fig. 1, when the front end of any key-lever in the righthand group, for instance, is depressed the turning of the corresponding indicator forward from normal position will swing the arm of the lever C toward the left to a position slightly to the left of the upper end of the pin 1* of the operated key. As the arm D approaches its limit of movement toward the left the indicator-rod corresponding to the operated key-lever will be struck and lifted by the rear end of the lever and its stop-pi n 1 projected upward through the plate M into the return path of the arm D and the engagement of the supporting-wing K with the collar of the lifted indicator-rod will maintain the rod in elevated position with its pin 1 in the path of the arm. D XVhen the operated key-lever is now released and permitted to return to normal position, the indicator will turn backward with the parts (under the influence of suitable springs acting upon the indicators and hereinafter referred to) until the arm D contacts with the stop-pin 1 which has been projected into its path, whereupon the arm D and indicator-wheel geared to it will be arrested and the key-lever and parts moving with it permitted to move on to normal position. The arrangement of the stop-pins 1 and the arms H which carry them, is best shown in Fig. 1 and is such that the stop-pin of the indicator-rod corresponding to any given key-lever will serve to arrest the corresponding indicator-wheel in its return movement toward normal position at such a point as will cause the indicator-wheel to expose to view the number representing the value of such key-lever. Vhen a keylever in another group is operated, the sup porting-wing K will be tripped, as before explained, and the previously-lifted indicatorrod will be released and dropped back to normal position, withdrawing its stop-pin I from the path of the arm D engaged with it and permitting the indicator-wheel geared to such arm to return to normal position, while the indicator-wheel corresponding to the newlyoperated key-lever will be brought in the manner before described to position to indicate the value of such key-lever.

The size and proportions of the pinions S and sector-racks A are such that the down- .ward stroke of the front end of any key-lever will turn the corresponding indicator forward a considerable distance beyond the position necessary to indicate the value of such keylever to thereby afford ample time and room for the stop-pin upon the indicator-rod to be lifted into the path of return movement of the arm D geared to such indicator. For instance, when the 5 key is depressed the indicator will be turned forward far enough to bring its number 7 or number 8 opposite the sight-opening, and when the keylever is returned the indicator will return toward normal position until arrested at the proper point to expose its number 5 to view. It will be understood from this that the graduated or differential movements of the rocking frame I, which are essential to the registration of the values of the different key-levers, are not essential to the indication of their values by the mechanism which has been described, the operation of which mechanism would remain substantially the same if the rocking frame I and sector-rack A were moved the same distance by the operation of one key as by the operation of another, it being only essential that the indicator shall be moved far enough beyond the desired indicating position to permit the stoppin of the operated key-lever to be projected into the return-path of its arm D and this may be accomplished either by moving the indicator only slightly beyond indicating position or by moving it to its maximum limit at each operation regardless of the value of the key-lever.

Each indicator is in the present instance shown provided not only with the nine digits and a cipher, as usual, but also with a letter corresponding to some one of the special keys. There are indicator-rods and stop-pins provided for each of the special keys, excepting the left-hand special key, marked No sale, in Fig. 1. The right-hand indicator in the lower set bears the letter P to correspond with the Paid out key, the middle indicator bears the letter R to correspond to the Received on accountkey, and the lefthand indicator bears the letter O to correspond to the Change key. The corresponding indicators in the upper set bear the same letters. As shown in the keys of the righthand indicator P in Fig. 2, the letter upon each indicator is located immediately at the right of the cipher, whichisnormally exposed to view, so that the letter will be brought opposite the sight-opening at the first forward movement of the indicatorin the direction of the arrow. Now each of the three special keys which cooperate with the indicators is provided with a pin J, the same as the cash key levers; but such pin is located lower down upon the finger or vertical extension G of the lever than is the pin J upon the cashkey lever of lowest value. It will be seen in Fig. 3 that there are three sets of ten key-levers, each provided with pins J. The nine right-hand key-levers in each of these sets in Fig, 3 are the cash-key levers, while the ex treme left-hand lever in each set is the special key, and it will be seen that the pin J upon the latter is the lowest one in each series. It results from this that when any one of the three special keys is operated its pin J will not engage and move the corresponding rocking frame I until the rear end of the lever has very nearly reached the limit of its upward movement, and consequently the frames 1 are given but very slight movements by the operations of the special keys. These movements are just sufficient to cause the racks A carried by the frames, to turn the indicator-wheels far enough to carry the let ters upon them to the left beyond the sightopening, Fig. 2, and permit the stop-pin upon the indicator-rod corresponding to the special key to be projected behind or into the returnpath of the arm D of the lever 0 geared to the indicator, such stop-pins upon the indicator-rods of the special keys being the extreme right-hand pin 1 in each of the three series shown in Fig. 1. The movements given the rocking frames by the special keys will of course throw forward the sector-racks K, which actuate the registering-wheels, Fig. 5; but the movement given these racks will not be sufficient to cause the racks to engage the pinions upon the registering-wheels, and thus no movement will be imparted to the registering-wheels upon the operation of any one of the special keys.

It will be understood that an indicator cannot at the same time expose to View both a number and its letter corresponding to one of the special keys. It therefore results in the present machine that no one of the special keys can be operated at the same time or in connection with any cash-key lever which cooperates with the same indicator as does the special key.

In the normal position of the indicators the arms D rest against fixed stop-pins Q upon the upper side of the frame-plate M.

The connection between the indicators 0 of the. upper set and the indicators P of the lower set,'by means of which the indicators representing the same denominations of value are caused to turn together, so that the amount indicated at the front of the machine by the lower indicators will also be indicated at the rear of the machine by the upper indicators, may be next described as follows: The two middle indicators, Figs. 1, 2, and 5, are both fast upon the middle spindle Y, (or upon the sleeve X, fast upon said spindle,) so that those two indicators turn together. As heretofore explained, the two end indicators P in the lower set are fast upon the end spindles; but the two end indicators 0 in the upper set are loose upon these spindles and free to turn thereon independently of the indicators P beneath them. In the manner and by the means-hereinafter described the upper left-hand indicator 0 in Fig. 2 is geared to the lower right-hand indicator P, so that the two turn together, while the upper righthand indicator 0 is geared to the lower lefthand indicator 1, so that those two indicators turn together. As seen in Fig. 1, the right-hand spindle Y has fast upon it a pini011 R with which meshes a rack formed upon one end of a longitudinally-sliding bar 8*, which has formed upon its opposite end a similar rack meshing with a pinion T fast upon the vertically-extended hub or sleeve of the left-hand indicator 0. Inasmuch as the lower right-hand indicator 1? is fast upon the right-hand spindle Y, it follows that by means of the pinions and rack-bar above de scribed the two indicators are geared together. The rack-bar S rests and travels upon the upper surface of the top plate Z and is held in position against the pinions RP T and guided in its longitudinal movements by screws V on the plates W. A coiled spring W connected at one end to the frame-plate Z and at its opposite end to the rack-bar S pulls the latter toward the right and yieldingly holds the parts in normal position and also serves to return them to such position after they have been removed therefrom and released. The lower left-hand indicator P is likewise geared to the upper right-hand indicator O by means of a similar slidingrackbar X (shown partly in full and. partly in dotted lines in Figs. 1 and f3 and in section in Figs. 5 and 6,) which rack-bar meshes at its left-hand end with a pinion Y fast upon the left-hand spindle Y, Fig. 0, and at its righthand end with a pinion Z, fast upon the lower end of the hub or sleeve of the upper righthand indicator 0, Fig. 2. In this manner the lower left-hand indicator I and upper right-hand indicator 0 are geared together and move in unison. A coiled spring Z (dotted lines, Figs. 1 and 9) pulls the rack-barX toward the left and aids the spring W heretofore described, in returning the parts to normal position.

It results from the foregoing connection between the indicators of the two sets that when any indicator in the lower set is turned to expose a given number to view at the front of the machine the corresponding indicator in the upper set will be turned at the same time to expose the same number at the rear of the machine.

Inasmuch as the two middle indicators are not connected with the rack-bars above described, an d consequently are not acted upon by the springs V and Z, connected to said bars, a special spring is provided for holding the middle indicators in and returning them to normal position, such spring being a coiled spring Z, Figs. 1, 2, and 3, secured at its right-hand end to the framework of the machine and connected at its left-hand end to a pin upon the rack-lever (J geared to the middle indicator-spindle.

Mounted to slide transversely of the machine in front and in rear of the indicators are two screen-plates A313 The front plate A is provided with three sight-openings 0 adapted to cooperate with the three indicators P in the lower set and so arranged that when the'plate is in normal position a single number or letter upon each of these indicators will be exposed through such openings. The rear plate B is provided with three similar sight-openings D adapted to cooperate in like manner with the indicators 0 of the upper set, Fig. 8. The two plates are rigidly secured to each other by means of crosspieces E Figs. 1, 5, and (5, and at their lower edges they rest and travel upon the outer ends of cross-bars F secured to the upper side of the plate M, Figs. 1, 3, and 4:. At their upper edges the plates are guided by cross-bars G", secured to the under side of the top frame-plate Z A coiled spring 11 Fig. 1, secured at its right-hand end to the fixed cross-bar G3 and at its left-hand end to the cross-piece E connecting the plates A B pulls said plates toward the right and serves to yieldingly hold them in and return them to normal position. Near their righthand ends the two plates are connected by a cross-rod 1 Figs. 1, 2, and 1-, which rod is embraced by the slotted upper end of a lever J", which is pivoted at K to a bracket upon the upper side of the frame-plate M, Figs. 2 and 4t. Projecting from the forward side of the ICC lever J is a stud L (surrounded by an antifriction-collar,) which is adapted to cooperate with a cam-shaped plate M rigidly secured to and carried by the upper end of a vertical rod N Figs. 2 and 4, which rod is connected at its lower end by a pivoted link 0 to the universal bar F, heretofore described, with the result that when the front end of any keylever is depressed the rod N will be lifted by the bar F and will return to normal position with said bar when the key-lever is released. The rod N is guided in its vertical movements by a bracket P secured to the side plate of the framework and by the frame-plate M, through openings in which bracket and frame-plate the rod passes. lVhenever the rod N is lifted by the operation of any one of the key-levers, the cam-plate M carried by its upper end, will contact with the stud L upon the forward side of the lever J Fig. 2, and rock said lever toward the left, causing its upper end by its engagement with the rod 1 of the screen-plates to slide said plates in that direction and carry their sight-openings away from the indicating-points, and thereby hide the indicators from view. This is effected at the beginning; of the downward stroke of any key-lever, and the screen-plates will be held in this position with the indicators hidden from view until the operated keylever is returned to approximately normal position. It results from this that at each operation of the machine the indicators are hidden from View at substantially the beginning of the operation and not exposed to view until it is substantially completed.
